Description

  The present invention relates to a water absorbent sheet for fresh foods such as seafood and meat.

  In general, fresh foods such as seafood and meat are often sold frozen in supermarkets and fresh food markets, etc., but after thawing frozen seafood and meat There are many cases of selling. When thawing the fresh food, especially when seafood, meat, etc. are thawed, a soup such as blood flows out called drip. When this drip comes into contact with the fresh food, only the contact portion of the fresh food is discolored, resulting in poor appearance and freshness. Moreover, when this fresh food was eaten, it was easy to become watery and the texture and taste were easy to fall. On the other hand, when purchasing and eating fresh food such as frozen seafood and meat, if the frozen product is thawed, a drip will flow out in the same manner as described above. Only the contact area is discolored, and when this fresh food is eaten, it becomes watery and the texture and taste are lowered. At this time, in general, the drip is absorbed each time with a cloth, bleaching, kitchen paper, etc., but when the drip is absorbed with a cloth, etc., the color of blood bleeds into the entire cloth, it looks bad and the odor of the drip also oozes. It was easy to become uncomfortable.

For this reason, the thing which spread the water absorption sheet | seat and the drip absorption sheet | seat under it along with fresh foods, such as seafood and meat, is sold. An example of this drip absorbing sheet is JP-A-11-243850. This is a sheet in which an absorbent is placed on a water-impermeable back material, and a water-permeable surface material is placed on the absorbent, and dyed water is added to the central portion of the sheet at a rate of 5 ml / 3 min. When dripped, it is a drip absorbent sheet in which the dyeing part on the sheet 10 minutes after dropping is 120 cm ² or less, and silicon dioxide is mixed into the absorber. In addition, as the absorbent body, a natural fiber such as hemp, cotton or pulp, a regenerated fiber such as rayon or acetate, or an aggregate of synthetic fibers is used. For example, polyethylene fiber is mixed with pulp fiber. However, in order to suppress thickening, the amount of fibers is set to a certain amount or less. This purpose is used for freezing and thawing fresh food and the like, and can be thawed in a good state. However, it only absorbs the drip of fresh food such as seafood and meat and prevents the drip from spreading.

On the other hand, as a water-absorbing sheet that also plays a role other than absorbing the drip of fresh food, for example, there is JP-A-11-285368, which is an antibacterial water-absorbing sheet used for improving the shelf life of fresh food and other foods. The structure consists of a cyclodextrin clathrate containing an antibacterial and volatile oily antibacterial agent and a dextrin adsorbent adsorbing an antibacterial and volatile oily antibacterial agent on a water absorbent sheet-like member. A natural resin is contained together with a binder. However, the cyclodextrin is expensive and expensive to manufacture. In the past, in order to coat or carry a volatile antibacterial agent or antioxidant on a nonwoven fabric or paper, it must be included in an expensive cyclodextrin.

  An object of the present invention is to provide a water-absorbent sheet for fresh food that can be thawed in a good state, can contribute to improving the shelf life of the food, and can be manufactured at low cost.

  The present invention has been made in view of the above situation, that is, a structure in which a water-absorbent resin and powdered wasabi are mixed in a bag body having water permeability. The contents may be composed of 100 parts by weight of a water-absorbent resin and 0.005 to 20 parts by weight of powdered wasabi. Good. Further, it is preferable to use a nonwoven fabric, paper, or a porous plastic film as the bag body, but the bag body is formed of a non-water-permeable plastic film and the other surface is water-permeable nonwoven fabric or porous. It may be made of a processed plastic film.

  The water-absorbent resin (1) is obtained by enclosing the water-absorbent resin (1) and the powdered wasabi (2) mixed in the bag body (3) having water permeability. Enables high water absorption to absorb food drip (sashimi juice and juice when dissolved), and even if powdered wasabi (2) is placed in a breathable bag (3) Since (2) does not generate volatile substances, the encapsulation and storage properties are good. On the other hand, powdered wasabi (2) generates volatile substances that have the effect of wasabi only when moisture such as drip is absorbed during use, and has the antibacterial and antioxidative effects of wasabi. A holding effect is obtained. Since the water-absorbing resin (1) having a high water-absorbing power and the inexpensive powdered wasabi (2) are mixed in this way, fresh foods can be thawed in a good state and the shelf life of those foods can be improved. It can contribute and can be manufactured at low cost.

  According to claim 2, the contents of the water-absorbent resin (1) and 0.005 to 20 parts by weight of powdered wasabi (2) are almost completely discharged. Since it is possible to absorb, the drip does not continue to come into contact with the fresh food as in the past, and it is possible to suppress the discoloration of the fresh food and the decrease in the freshness, as well as the conventional wateriness and food. The feeling can be prevented from being lowered, the appearance is good, and the odor of the drip is hardly produced.

  As shown in claim 3, it is possible to put the number of packages according to the drip appearance of fresh food by dividing the contents into a plurality of packages inside the bag body (3) It becomes. Accordingly, the capacity to be put together with the fresh food can be reduced, and the cost of the water absorbent sheet for fresh food can be reduced. Therefore, the sales price of the fresh food can be made lower than before, which can contribute to sales promotion.

  By using a non-woven fabric, paper, or a porous plastic film as the bag (3) as shown in claim 4, the cost can be reduced.

  The one side of the bag body (3) is made of a non-water-permeable plastic film as in claim 5, and the other side is made of a water-permeable non-woven fabric or a porous plastic film, thereby printing on the one side. Therefore, it is possible to produce a prominent product by printing advertisements, product names, colors, or the like. In addition, it is possible to print precautions clearly.

  1 and 2 are diagrams showing an embodiment of the present invention, which will be described. (1) is a water-absorbing resin, and the water-absorbing resin (1) is preferably one that expands and gels when absorbed, and a general water-absorbing resin for a cold insulating material may be used. For example, the main component is a cellulose-based water-soluble polymer substance such as an acrylic acid-based compound, a natural thickener, carboxymethylcellulose sodium salt (CMC), or the like. (2) is commercially available powdered wasabi, and the amount of powdered wasabi (2) mixed is 0.005 to 20 parts by weight with respect to 100 parts by weight of the water-absorbent resin (1). Although it is good, 0.01 to 5 parts by weight is particularly preferable. When the mixing amount of the powdered wasabi (2) is 0.005 parts by weight or less, the effect of wasabi is reduced, and when it is 20 parts by weight or more, the cost is easily increased and wasabi volatiles increase. There is a risk of quality effects on food. (3) is a bag body having water permeability, and the bag body (3) is for enclosing the mixed content of the water-absorbent resin (1) and the powdered wasabi (2). It is preferable that the product is enclosed as a package type divided into a plurality of parts inside the bag (3). Further, as the material of the bag (3), it is preferable to use a non-woven fabric, paper, or a porous plastic film, but one side of the bag (3) is a non-permeable plastic film and the other side is a water-permeable non-woven fabric. Or a porous plastic film. As this plastic film, nylon polypropylene or nylon ethylene may be used.

  Next, how to make the product of the present invention will be described. First, the amount of powdered wasabi (2) mixed is 0.03 parts by weight with respect to 100 parts by weight of the water-absorbent resin (1), and the mixture and the bag (3) are prepared. As the bag (3) at this time, it is preferable to use a plastic film of nylon ethylene, but one side is non-permeable, the other side is permeable, and one side is non-permeable. Prepare one printed on Next, a predetermined amount of contents are put into the bag (3) and sealed by a method such as thermocompression bonding. At this time, not only the contents are enclosed in the bag (3), but also the contents may be enclosed as a package type in which the interior of the bag (3) is divided into a plurality as shown in FIG. As described above, the powdered wasabi (2) can be easily mixed with the water-absorbent resin (1), and even if it is simply enclosed in the bag (3), the wasabi effect is not lost. It is not necessary to use expensive cyclodextrins, and the manufacturing cost is low.

  The operation of the present invention will be described with reference to FIG. First, the product of the present invention shown in FIG. 3 (a) is put in a tray or the like together with frozen fresh food. At this time, it may be placed under or near fresh food. Thereafter, as the frozen fresh food is thawed, a drip of fresh food flows out. The drip is almost absorbed by the water absorbent resin (1) which is the contents of the bag (3) and also absorbed by the powdered wasabi (2). Then, the water absorbent resin (1) gradually expands as the drip is absorbed [see FIG. 3 (b)]. Also, the powdered wasabi (2) returns to the original kneaded wasabi state as the drip is absorbed, and generates volatile components. This generated volatile component wraps fresh food as an atmosphere, so it has antibacterial and antioxidative effects, which are effective for wasabi, and the fresh food can be kept fresh. . At this time, the water-absorbing resin (1) has a high water-absorbing power, and the drip of the fresh food can be absorbed almost completely in a very short time, so that the conventional drip will never touch the fresh food and change its color. In addition, there is no fear that the fresh food will become watery, or that the texture and taste will not deteriorate. Further, the wasabi effect of the powdered wasabi (2) is that when the water absorbent resin (1) absorbs water and expands, the powdered wasabi (2) mixed with the water absorbent resin (1) or the powdered wasabi (2) that has absorbed water Even if the powdered wasabi (2) mixed on the inner side of the water absorbent resin (1) absorbs water and emits volatile components, the powdered wasabi (2) The area around which the water-absorbing resin (1) comes into contact with the water-absorbing resin is reduced, the volatile component is gradually emitted without immediately coming out, and the effective period of wasabi is prolonged. Therefore, the shelf life of fresh food is improved. The water-absorbing resin (1) expands by absorbing the drip until it becomes several to several tens of times as shown in FIG. 3 (c).

It is explanatory drawing which shows embodiment of the packaging type of this invention. It is an expanded sectional view of FIG. It is explanatory drawing which shows the state which water absorbing resin and powder wasabi absorb liquids, such as a drip, in a bag.
